A crossover between TMNT and RWBY. Deep below the sewers in the city of Vale, there lives four mutant turtles along with a mutant rat. For many years, they have lived in secret. That was until the day when they were forced to go to the surface. It was then that they found themselves taking on the threats that endanger the kingdom. While also making some new friends with four certain huntresses.

In a city, known as Tokyo, punks roam around the streets with their battery-powered roller blades and spray-painting graffiti. However, with the rise of Gouji Rokkaku, and his upcoming Expo, crackdowns against these street punks are happening left and right. Amidst all this, a team of rudies, known as the GGs, rise up, and prepare to save the streets....and probably the whole world.
